DAMPER FOR BUCKLING RESTRAINING BRACE
PROBLEM TO BE SOLVED: To provide a damper for a buckling restraining brace that enhances energy absorption performance while suppressing a rise in compressive axial force, and enables control of deviation of a buckling restraining material in a material axis direction.SOLUTION: A damper for a buckling restraining brace includes a core material 2 and a buckling restraining material 3 for preventing buckling of the core material 2. The core material 2 includes a plasticizing part extending in an axial line O1 direction and absorbing vibration energy by plastically deforming when the vibration energy is exerted, and a pair of connection parts 5 provided respectively on both end sides in the axial line O1 direction and having a connection hole 6 for connecting with a building frame. The connection hole 6 formed respectively on the pair of connection parts 5 of the core material 2 is formed as a long hole extending in the axial line O1 direction, and both end sides in the axial line O1 direction are configured as movable ends.SELECTED DRAWING: Figure 1
【課題】圧縮軸力の上昇を抑えつつエネルギー吸収性能を高め、座屈拘束材の材軸方向のズレの制御を可能にする座屈拘束ブレースダンパーを提供する。【解決手段】芯材２と、芯材２の座屈を防止するための座屈拘束材３とを備え、芯材２が、軸線Ｏ１方向に沿って延設され、振動エネルギーが作用した際に塑性変形してこの振動エネルギーを吸収する塑性化部と、軸線Ｏ１方向両端部側にそれぞれ設けられ、建物の架構に接続するための接合孔６を有する一対の接合部５とを備え、芯材２の一対の接合部５にそれぞれ形成された接合孔６を軸線Ｏ１方向に延びる長孔状に形成し、軸線Ｏ１方向両端部側をともに可動端として構成する。【選択図】図１
